Dispositions

During the nine months ended September 30, 2015, we completed the sales of four MH communities. Pursuant to Accounting Standards Update ("ASU") 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) - Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity"("ASU 2014-08"), the disposals of the communities do not qualify for presentation as a discontinued operation, as the sales do not have a major impact on our operations and financial results and do not represent a strategic shift. Additionally, the communities are not considered an individually significant component and therefore do not qualify for presentation as a discontinued operation. A gain of $26.9 million is recorded in "Gain on disposition of properties, net" in our Consolidated Statements of Operations. The table below lists the communities we have disposed of during the nine months ended September 30, 2015.

3.      Collateralized Receivables and Transfers of Financial Assets

We completed various transactions with an unrelated entity involving our notes receivable under which we received cash proceeds in exchange for relinquishing our right, title, and interest in certain notes receivable. We have no further obligations or rights with respect to the control, management, administration, servicing, or collection of the installment notes receivable. However, we are subject to certain recourse provisions requiring us to purchase the underlying homes collateralizing such notes, in the event of a note default and subsequent repossession of the home by the unrelated entity. The recourse provisions are considered to be a form of continuing involvement, and therefore these transferred loans did not meet the requirements for sale accounting. We continue to recognize these transferred loans on our balance sheet and refer to them as collateralized receivables. The proceeds from the transfer have been recognized as a secured borrowing.

In the event of a note default and subsequent repossession of a manufactured home by the unrelated entity, the terms of the agreement require us to repurchase the manufactured home. Default is defined as the failure to repay the installment note receivable according to contractual terms. The repurchase price is calculated as a percentage of the outstanding principal balance of the collateralized receivable, plus any outstanding late fees, accrued interest, legal fees, and escrow advances associated with the

12

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

installment note receivable.  The percentage used to determine the repurchase price of the outstanding principal balance on the installment note receivable is based on the number of payments made on the note. In general, the repurchase price is determined as follows:

Number of Payments	Repurchase Percentage
Fewer than or equal to 15	100	%
Greater than 15 but less than 64	90	%
Equal to or greater than 64 but less than 120	65	%
120 or more	50	%

The transferred assets have been classified as Collateralized receivables, net and the cash proceeds received from these transactions have been classified as a Secured borrowing within the Consolidated Balance Sheets. The balance of the collateralized receivables was $138.2 million (net of allowance of $0.6 million) and $123.0 million (net of allowance of $0.7 million) as of September 30, 2015 and December 31, 2014, respectively. The receivables have a weighted average interest rate and maturity of 10.2% and 15.2 years as of September 30, 2015, and 10.4% and 14.6 years as of December 31, 2014.

The outstanding balance on the secured borrowing was $138.9 million and $123.7 million as of September 30, 2015 and December 31, 2014, respectively.

The collateralized receivables earn interest income, and the secured borrowings accrue interest expense at the same interest rates. The amount of interest income and expense recognized was $3.3 million and $3.0 million, and $9.6 million and $8.6 million for the three and nine months endedSeptember 30, 2015 and 2014, respectively.  

The balances of the collateralized receivables and secured borrowings fluctuate. The balances increase as additional notes receivable are transferred and exchanged for cash proceeds. The balances are reduced as the related collateralized receivables are collected from the customers, or as the underlying collateral is repurchased. The change in the aggregate gross principal balance of the collateralized receivables is as follows (in thousands):

	Nine Months Ended

6.      Investment in Affiliates

Origen Financial Services, LLC (“OFS LLC”)

At September 30, 2015 and December 31, 2014, we had a 22.9% ownership interest in OFS LLC, an entity formed to originate manufactured housing installment contracts. We have suspended equity accounting as the carrying value of our investment is zero.

Origen Financial, Inc. (“Origen”)

Through Sun OFI, LLC, a taxable REIT subsidiary, we own 5,000,000 shares of common stock in Origen, which approximates an ownership interest of 19%. We had suspended equity accounting for this investment as the carrying value of our investment was zero. In January 2015, Origen completed the sale of substantially all of its assets to an affiliate of GoldenTree Asset Management, LP and has announced its intention to dissolve and liquidate. During the second quarter of 2015, and as disclosed in a press release on March 30, 2015, Origen made an initial distribution of $1.50 per share to its stockholders of record as of April 13, 2015, retaining approximately $6.2 million for expected dissolution, wind down costs, expenses, and contingencies. Depending on the actual cost of estimated wind down expenses, Origen may make one or more additional interim distributions of excess cash to stockholders prior to completing liquidation. Upon completion of liquidation, Origen will distribute remaining cash, if any, to stockholders. During the second quarter of 2015, we received an initial distribution of $7.5 million from Origen.

7.      Consolidated Variable Interest Entities

Variable interest entities ("VIEs") that are consolidated include Rudgate Village SPE, LLC, Rudgate Clinton SPE, LLC, Rudgate Clinton Estates SPE, LLC (the “Rudgate Borrowers”), and Wildwood Village Mobile Home Park ("Wildwood"). We evaluated our arrangements with these properties under the guidance set forth in FASB Accounting Standard Codification ("ASC") ASC Topic 810 "Consolidation". We concluded that the Rudgate Borrowers and Wildwood qualify as VIEs as we are the primary beneficiary and hold controlling financial interests in these entities due to our power to direct the activities that most significantly impact the economic performance of the entities, as well as our obligation to absorb the most significant losses and our rights to

Collateralized Term Loans

In August 2015, we entered into an agreement to borrow $87.0 million in mortgage debt that will be secured by five communities at an interest rate of 4.06% for a term of 25 years. This loan will close in two separate closings. In September 2015, we completed the first closing for $51.2 million secured by four communities and the second closing for $35.8 million is scheduled to close in December 2015.

In May 2015, we defeased a total of $70.6 million aggregate principal amount of collateralized term loans with an interest rate of 5.32% that were due to mature on July 1, 2016, releasing 10 communities. As a result of the transaction we recognized a loss on debt extinguishment of $2.8 million that is reflected in our Consolidated Statement of Operations.

In March 2015, in relation to the acquisition of Meadowlands (see Note 2), we assumed a $6.3 million mortgage with an interest rate of 6.5% and a remaining term of 6.5 years. Also, in relation to this acquisition, we entered into a note payable with the seller for $2.4 million that bears no interest but is payable in three equal yearly installments beginning in March 2016.

In January 2015, in relation to the acquisition of the Green Courte properties (see Note 2), we refinanced approximately $90.8 million of mortgage debt on 10 of the communities (resulting in proceeds of $112.3 million) at a weighted average interest rate of 3.87% per annum and a weighted average term of 14.1 years. We also assumed approximately $201.4 million of mortgage debt at a weighted average interest rate of 5.74% and a weighted average remaining term of 6.3 years.

Secured Borrowing

See Note 3, "Collateralized Receivables and Transfers of Financial Assets", for additional information regarding our collateralized receivables and secured borrowing transactions.

Preferred OP Units

Included in preferred OP units is $34.7 million of Aspen preferred OP units issued by the Operating Partnership which are convertible into 509,676 shares of the Company's common stock. Subject to certain limitations, at any time prior to January 1, 2024, the holder of each Aspen preferred OP unit at its option may convert such Aspen preferred OP unit into: (a) if the market price of our common stock is $68.00 per share of less, 0.397 common OP units, or (b) if the market price of our common stock is greater than $68.00 per share, that the number of common OP units determined by dividing (i) the sum of (A) $27.00 plus (B) 25% of the amount by which the market price of our common stock exceeds $68.00 per share, by (ii) the per-share market price of our common stock. The current preferred distribution rate is 6.5%.

Lines of Credit

In August, 2015, we amended and restated our senior revolving credit facility with Citibank, N.A. and certain other lenders in the amount of $450.0 million, comprised of a $392.0 million revolving loan and $58.0 million term loan (the "Facility"). The Facility has a four year term ending August 19, 2019, which can be extended for two additional six-month periods at our option, subject to the satisfaction of certain conditions as defined in the credit agreement. The credit agreement also provides for, subject to the satisfaction of certain conditions, additional commitments in an amount not to exceed $300.0 million. If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the Facility may be increased up to $750.0 million. The Facility bears interest at a floating rate based on the Eurodollar rate plus a margin that is determined based on our leverage ratio calculated in accordance with the credit agreement, which can range from 1.40% to 2.25% for the revolving loan and 1.35% to 2.20% for the term loan. As of September 30, 2015, the margin on our leverage ratio was 1.45% and 1.40% on the revolving and term loans, respectively. We had $142.0 million on the revolving loan and $25.0 million on the term loan totaling $167.0 million in borrowings as of September 30, 2015, with a weighted average interest rate of 1.66%. As of December 31, 2014 there was no amount outstanding under our previous credit Facility.

The Facility provides us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under our line of credit, but does reduce the borrowing amount available. At September 30, 2015 and December 31, 2014, approximately $3.4 million and $3.2 million, respectively, of availability was used to back standby letters of credit.

We have a $12.0 million manufactured home floor plan facility renewable indefinitely until our lender provides us at least a twelve month notice of their intent to terminate the agreement. The interest rate is 100 basis points over the greater of the prime rate as quoted in the Wall Street Journal on the first business day of each month or 6.0%. At September 30, 2015, the effective interest rate was 7.0%.  There was no outstanding balance at September 30, 2015 and there was $5.8 million at December 31, 2014.

Also in June 2015, we entered into an At the Market Offering Sales Agreement (the "Sales Agreement") with BMO Capital Markets Corp., Merrill Lynch, Pierce, Fenner and Smith Incorporated and Citigroup Global Markets Inc. (collectively, the "Sales Agents"). Pursuant to the Sales Agreement, we may offer and sell shares of our common stock, having an aggregate offering price of up to $250.0 million, from time to time through the Sales Agents. Each Sales Agent is entitled to compensation in an agreed amount not to exceed 2.0% of the gross sales price per share for any shares sold through it from time to time under the Sales Agreement. Concurrently, the At the Market Offering Sales Agreement dated May 10, 2012, as amended among the Company, the Partnership, BMO Capital Markets Corp. and Liquidnet, Inc., was terminated.

In January 2015, in connection with the Green Courte second closing, we issued 4,377,073 shares of common stock at an issuance price of $50.00 per share and 5,847,234 shares of Series A-4 Preferred Stock at an issuance price of $25.00 per share. The Series A-4 Preferred Stock stockholders receive a preferred return of 6.5%. In addition, one of the Green Courte Partners funds purchased 150,000 shares of our common stock and 200,000 Series A-4 preferred OP units for an aggregate purchase price of $12.5 million. As noted above, in July 2015, the Company repurchased 4,066,586 shares of the Series A-4 Preferred Stock.

If certain change of control transactions occur or if our common stock ceases to be listed or quoted on an exchange or quotation system, then at any time after November 26, 2019, we or the holders of shares of Series A-4 Preferred Stock and Series A-4 preferred OP units may cause all or any of those shares or units to be redeemed for cash at a redemption price equal to the sum of (i) the greater of (x) the amount that the redeemed shares of Series A-4 Preferred Stock and Series A-4 preferred OP units would have received in such transaction if they had been converted into shares of our common stock immediately prior to such transaction, or (y) $25.00 per share, plus (ii) any accrued and unpaid distributions thereon to, but not including, the redemption date. The Series A-4 preferred OP units are inclusive of its pro-rata share of net income of $0.3 million and distributions of $1.0 million for the nine months ended September 30, 2015.

In November 2004, our Board of Directors authorized us to repurchase up to 1,000,000 shares of our common stock. We have 400,000 common shares remaining in the repurchase program. No common shares were repurchased under this buyback program during the nine months ended September 30, 2015 or 2014. There is no expiration date specified for the buyback program.

Common OP unit holders can convert their common OP units into an equivalent number of shares of common stock at any time. During the nine months ended September 30, 2015, there were 99,404 common OP units converted to shares of common stock. No such units were converted during the nine months ended September 30, 2014.

10.      Share-Based Compensation

At the Annual Meeting of Stockholders held on July 20, 2015, the stockholders approved Sun Communities, Inc. Equity Incentive Plan ("2015 Equity Plan"). The 2015 Equity Plan had been adopted by the Board and was effective upon approval by our stockholders. The 2015 Equity Plan replaced the Sun Communities, Inc. Equity Incentive Plan adopted in 2009. The maximum number of shares of common stock that may be issued under the 2015 Equity Plan is 1,750,000 shares of our common stock.

In September 2015, we granted 4,500 shares of restricted stock to key employees under our 2015 Equity Plan. The shares had a fair value of $67.29 per share and will vest as follows: September 29, 2018: 35%; September 29, 2019: 35%; September 29, 2020: 20%; September 29, 2021: 5%; and September 29, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In July 2015, we granted 20,000 shares of restricted stock to an executive officer under our Sun Communities, Inc. Equity Incentive Plan ("2009 Equity Plan"). The shares had a fair value of $67.57 per share and will vest as follows: July 16, 2018: 35%; July 19, 2019: 35%; July 16, 2020: 20%; July 16, 2021: 5%; and July 16, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In May 2015, we granted 25,000 shares of restricted stock to an executive officer under our 2009 Equity Plan. The shares had a fair value of $62.94 per share and will vest as follows: May 19, 2018: 35%; May 19, 2019: 35%; May 19, 2020: 20%; May 19, 2021: 5%; and May 19, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In April 2015, we granted 145,000 shares of restricted stock to our executive officers under our 2009 Equity Plan. The shares had a fair value of $63.81 per share. Half of the shares will vest as follows: April 14, 2018: 20%; April 14, 2019: 30%; April 14, 2020: 35%; April 14, 2021: 10%; and April 14, 2022: 5%. The remaining 72,500 shares are subject to market and performance conditions which vest over time through April 2020. Share-based compensation for restricted stock awards with performance conditions is measured based on an estimate of shares expected to vest. We estimate the fair value of share-based compensation for restricted stock with market conditions using a Monte Carlo simulation.

In February 2015, we granted 19,800 shares of restricted stock to our non-employee directors under our First Amended and Restated 2004 Non-Employee Director Option Plan. The awards vest on February 11, 2018, and had a fair value of $65.87 per share. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In January 2015, we granted 1,000 shares of restricted stock to key employees under our 2009 Equity Plan. The shares had a fair value of $65.48 per share and will vest as follows: January 8, 2018: 35%; January 8, 2019: 35%; January 8, 2020: 20%;

January 8, 2021: 5%; and January 8, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

During the nine months ended September 30, 2015 and 2014, 4,084 and 4,904 shares of common stock, respectively, were issued in connection with the exercise of stock options, and the net proceeds received during both periods was $0.1 million.

The vesting requirements for 85,958 restricted shares granted to our executives and employees were satisfied during the nine months ended September 30, 2015.

11. Segment Reporting

We group our operating segments into reportable segments that provide similar products and services. Each operating segment has discrete financial information evaluated regularly by the Company's chief operating decision maker in evaluating and assessing performance. We have two reportable segments: (i) Real Property Operations and (ii) Home Sales and Rentals. The Real Property Operations segment owns, operates, and develops MH communities and RV communities and is in the business of acquiring, operating, and expanding MH and RV communities.  The Home Sales and Rentals segment offers manufactured home sales and leasing services to tenants and prospective tenants of our communities. 

Transactions between our segments are eliminated in consolidation.  Transient RV revenue is included in the Real Property Operations segment revenues and is expected to approximate $39.3 million annually. In 2015, we recognized 22.4%, 17.4% and 45.2% during the first, second and third quarters, respectively. We expect to recognize 15.0% during the fourth quarter of 2015. In 2014, transient revenue was $31.6 million. We recognized 25.3% in the first quarter, 18.3% in the second quarter, 43.3% in the third quarter, and 13.1% in the fourth quarter.

12.    Income Taxes

We have elected to be taxed as a real estate investment trust (“REIT”) pursuant to Section 856(c) of the Internal Revenue Code of 1986 (“Code”), as amended. In order for us to qualify as a REIT, at least 95% of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute annually at least 90% of its REIT ordinary taxable income to its stockholders.

Qualification as a REIT involves the satisfaction of numerous requirements (i.e., some on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are only limited judicial or administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation which requires us to continually monitor our tax status. We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT for the quarter ended September 30, 2015.

As a REIT, we generally will not be subject to United States ("U.S.") federal income taxes at the corporate level on the ordinary taxable income we distribute to our stockholders as dividends. If we fail to qualify as a REIT in any taxable year, our taxable income could be subject to U.S. federal income tax at regular corporate rates (including any applicable alternative minimum tax). Even if we qualify as a REIT, we may be subject to certain state and local income taxes, U.S. federal income, and excise taxes on our undistributed income.

SHS, our taxable REIT subsidiary, is subject to U.S. federal income taxes. Our deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the bases of such assets and liabilities as measured by tax laws. Deferred tax assets are reduced, if necessary, by a valuation allowance to the amount where realization is more likely than not assured after considering all available evidence. Our temporary differences primarily relate to net operating loss carryforwards and depreciation. A federal deferred tax asset of $1.0 million is included in "Other assets, net," in our Consolidated Balance Sheets as of September 30, 2015 and December 31, 2014.

We had no unrecognized tax benefits as of September 30, 2015 and 2014. We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of September 30, 2015.

We classify certain state taxes as income taxes for financial reporting purposes. For instance, we record Texas Margin Tax as income tax in our financial statements, and recorded a provision for state income taxes of approximately $0.1 million for the three months ended September 30, 2015 and 2014, and $0.3 million for the nine months ended September 30, 2015 and 2014.

SHS is currently under examination by the Internal Revenue Service ("IRS") for the 2013 tax year. To date, we have not received any formal notices of proposed adjustments from the IRS related to this or any other examination periods.

13.    Earnings Per Share

We have outstanding stock options, unvested restricted shares, and Series A-4 Preferred Stock, and our Operating Partnership has outstanding common OP units, Series A-1 preferred OP units, Series A-3 preferred OP units, Series A-4 preferred OP units, Series C preferred OP units, and Aspen preferred OP Units, which, if converted or exercised, may impact dilution.

14. Derivative Instruments and Hedging Activities

Our objective in using interest rate derivatives is to manage exposure to interest rate movements thereby minimizing the effect of interest rate changes and the effect it could have on future cash flows. Interest rate caps are used to accomplish this objective. We do not enter into derivative instruments for speculative purposes nor do we have any swaps in a hedging arrangement.

The following table provides the terms of our interestrate derivative contracts that were in effect as of September 30, 2015:

Type	Purpose	Effective Date	Maturity Date	Notional  (in millions)		Based on	Variable Rate	Fixed Rate	Spread	Effective Fixed Rate

Cap	Cap Floating Rate	10/3/2011	10/3/2016	$	10.0	3 Month LIBOR	0.2830%	11.0200%	—%	N/A

In accordance with ASC Topic 815, "Derivatives and Hedging"("ASC 815"), derivative instruments are recorded at fair value in "Other assets, net" or "Other liabilities" on the Consolidated Balance Sheet. As of September 30, 2015 and December 31, 2014, the fair value of the derivatives was zero.

15.    Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts and notes receivable, accounts payable, derivative instruments, and debt.

ASC Topic 820 "Fair Value Measurements and Disclosures" ("ASC 820"), requires disclosure about how fair value is determined for assets and liabilities and establishes a hierarchy under which these assets and liabilities must be grouped, based on significant levels of observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's market assumption. This hierarchy requires the use of observable market data when available. These two types of inputs have created the following fair value hierarchy:

Level 1—Quoted unadjusted prices for identical instruments in active markets.

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.

Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The following methods and assumptions were used in order to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Derivative Instruments

The derivative instruments held by us are interest rate cap agreements for which quoted market prices are indirectly available. For those derivatives, we use model-derived valuations in which all significant inputs and significant value drivers are observable in active markets provided by brokers or dealers to determine the fair value of derivative instruments on a recurring basis (Level 2). See Note 14 for Derivative Instruments.

Installment Notes Receivable on Manufactured Homes

The net carrying value of the installment notes receivable on manufactured homes estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). See Note 4 for Installment Notes Receivable.

Long-Term Debt and Lines of Credit

The fair value of long-term debt (excluding the secured borrowing) is based on the estimates of management and on rates currently quoted, rates currently prevailing for comparable loans, and instruments of comparable maturities (Level 2). See Note 8 for Long-Term Debt and Lines of Credit.

Collateralized Receivables and Secured Borrowings

The fair value of these financial instruments offset each other as our collateralized receivables represent a transfer of financial assets and the cash proceeds received from these transactions have been classified as a secured borrowing on the Consolidated Balance Sheets. The net carrying value of the collateralized receivables estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). See Note 3 for Collateralized Receivables and Secured Borrowing.

Other Financial Instruments

The carrying values of cash and cash equivalents, accounts receivable, and accounts payable approximate their fair market values due to the short-term nature of these instruments.

16.    Recent Accounting Pronouncements

In April 2015, the FASB issued ASU 2015-03 "Interest - Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03"). This amendment requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. In August 2015, the FASB issued ASU 2015-15 "Interest - Imputation of Interest (Subtopic 835-30) Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements" ("ASU 2015-15"). This amendment provides additional guidance within ASU 2015-03 for debt issuance costs related to line of credit arrangements. These amendments are effective for fiscal years beginning after December 15, 2015, and interim periods within those years, with early adoption permitted. Entities should apply the amendments retrospectively. We are currently evaluating the potential impact these amendments will have on our Consolidated Financial Statements.

In February 2015, the FASB issued ASU No. 2015-02 "Consolidation (Topic 810) Amendments to the Consolidation Analysis" ("ASU 2015-02"). This amendment eliminates the deferral of FAS 167, which has allowed entities with interests in certain investment funds to follow the previous consolidation guidance in FIN 46(R), and makes other changes to both the variable interest model and the voting model. While the guidance is aimed at asset managers, it will affect all reporting entities that have variable interests in other legal entities (e.g., limited partnerships, similar entities and certain corporations). In some cases, consolidation conclusions will change. In other cases, reporting entities will need to provide additional disclosures about entities that currently aren’t considered VIEs but will be considered VIEs under the new guidance provided they have a variable interest in those VIEs. These amendments are effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. Entities may apply the amendments using either a modified retrospective approach or retrospectively. We are currently evaluating the potential impact this amendment will have on our Consolidated Financial Statements.

In August 2014, the FASB issued ASU 2014-15 "Disclosure of Uncertainties About an Entity's Ability to Continue as a Going Concern" ("ASU 2014-15"). This amendment requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date the financial statements are issued and provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. Certain disclosures will be required if conditions give rise to substantial doubt about an entity's ability to continue as a going concern. This amendment applies to all entities and are effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. We are currently evaluating the potential impact this amendment will have on our quarterly reporting process.

In May 2014, the FASB issued ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"). The objective of this amendment is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying this amendment, companies will perform a five-step analysis of transactions to determine when and how

revenue is recognized. This amendment applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC. This amendment is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period; early adoption is not permitted. An entity should apply the amendments using either the full retrospective approach or retrospectively with a cumulative effect of initially applying the amendments recognized at the date of initial application. We are currently evaluating the methods of adoption and the impact that the adoption of ASU 2014-09 may have on our Consolidated Financial Statements.

17.   Commitments and Contingencies

We are involved in various legal proceedings arising in the ordinary course of business. All such proceedings, taken together, are not expected to have a material adverse impact on our results of operations or financial condition.

18.   Subsequent Event

In October 2015, we completed the sale of three MH communities comprised of approximately 1,250 sites located in Indiana for $36.1 million.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of the consolidated financial condition and results of operations should be read in conjunction with the Consolidated Financial Statements and Notes thereto, along with our 2014 Annual Report. Capitalized terms are used as defined elsewhere in this Form 10-Q.

OVERVIEW

We are a fully integrated, self-administered and self-managed REIT. As of September 30, 2015, we owned and operated a portfolio of 251 developed properties located in 30 states throughout the United States, including 200 MH communities, 37 RV communities, and 14 properties containing both MH and RV sites.

We have been in the business of acquiring, operating, developing, and expanding MH and RV communities since 1975. We lease individual sites with utility access for placement of manufactured homes and RVs to our customers. We are also engaged through SHS in the marketing, selling, and leasing of new and pre-owned homes to current and future residents in our communities. The operations of SHS support and enhance our occupancy levels, property performance, and cash flows.

SIGNIFICANT ACCOUNTING POLICIES

We have identified significant accounting policies that, as a result of the judgments, uncertainties, and complexities of the underlying accounting standards and operations involved could result in material changes to our financial condition or results of operations under different conditions or using different assumptions. Details regarding significant accounting policies are described fully in our 2014 Annual Report.

SUPPLEMENTAL MEASURES

In addition to the results reported in accordance with GAAP, we have provided information regarding Net Operating Income (“NOI”) in the following tables. NOI is derived from revenues minus property operating and maintenance expenses and real estate taxes. We use NOI as the primary basis to evaluate the performance of our operations. A reconciliation of NOI to net income attributable to Sun Communities, Inc. common stockholders is included in “Results of Operations” below.

We believe that NOI is helpful to investors and analysts as a measure of operating performance because it is an indicator of the return on property investment and provides a method of comparing property performance over time. We use NOI as a key management tool when evaluating performance and growth of particular properties and/or groups of properties. The principal limitation of NOI is that it excludes depreciation, amortization, interest expense, and non-property specific expenses such as general and administrative expenses, all of which are significant costs, and therefore, NOI is a measure of the operating performance of our properties rather than of the Company overall.  We believe that these costs included in net income often have no effect on the market value of our property and therefore limit its use as a performance measure. In addition, such expenses are often incurred at a parent company level and therefore are not necessarily linked to the performance of a real estate asset.

NOI should not be considered a substitute for the reported results prepared in accordance with GAAP. NOI should not be considered as an alternative to net income as an indicator of our financial performance, or to cash flows as a measure of liquidity; nor is it indicative of funds available for our cash needs, including our ability to make cash distributions.  NOI, as determined and presented by us, may not be comparable to related or similarly titled measures reported by other companies.

We also provide information regarding Funds From Operations (“FFO”).  We consider FFO an appropriate supplemental measure of the financial and operational performance of an equity REIT. Under the National Association of Real Estate Investment Trusts (“NAREIT”) definition, FFO represents net income (loss) (computed in accordance with GAAP), excluding extraordinary items (as defined under GAAP), and gain (loss) on sales of depreciable operating property, plus real estate related depreciation and amortization (excluding amortization of financing costs), and after adjustments for unconsolidated partnerships and joint ventures. Management also uses FFO excluding certain items, a non-GAAP financial measure, which excludes certain gain and loss items that management considers unrelated to the operational and financial performance of our core business. We believe that this provides investors with another financial measure of our operating performance that is more comparable when evaluating period over period results. A discussion of FFO, FFO excluding certain items, a reconciliation of FFO to net income, and FFO to FFO excluding certain items are included in the presentation of FFO in our “Results of Operations" below.

RESULTS OF OPERATIONS

We report operating results under two segments: Real Property Operations and Home Sales and Rentals. The Real Property Operations segment owns, operates, and develops MH communities and RV communities throughout the U.S. and is in the business of acquiring, operating, and expanding MH and RV communities. The Home Sales and Rentals segment offers manufactured home sales and leasing services to tenants and prospective tenants of our communities. We evaluate segment operating performance based on NOI and gross profit.

SUN COMMUNITIES, INC.

REAL PROPERTY OPERATIONS – SAME SITE

A key management tool used when evaluating performance and growth of our properties is a comparison of Same Site communities. Same Site communities consist of properties owned and operated throughout 2015 and 2014.  The Same Site data may change from time-to-time depending on acquisitions, dispositions, management discretion, significant transactions, or unique situations. The Same Site data in this Form 10-Q includes all properties acquired prior to December 31, 2013 and which we have owned and operated continuously since January 1, 2014.

In order to evaluate the growth of the Same Site communities, management has classified certain items differently than our GAAP statements. The reclassification difference between our GAAP statements and our Same Site portfolio is the reclassification of water and sewer revenues from income from real property to utilities.  A significant portion of our utility charges are re-billed to our residents. We reclassify these amounts to reflect the utility expenses associated with our Same Site portfolio net of recovery.

The following tables reflect certain financial and other information for our Same Site communities as of and for the three months ended September 30, 2015 and 2014:

	Three Months Ended September 30,

⁽¹⁾    Occupied sites and occupancy % include MH and annual RV sites, and exclude transient RV sites, which are included in total developed sites.

⁽²⁾ Occupancy % excludes recently completed but vacant expansion sites.

⁽³⁾  Weighted average rent pertains to annual RV sites and excludes transient RV sites.

The 9.1% growth in NOI is primarily due to increased revenues of $5.9 million partially offset by additional expenses of $0.9 million.

Income from real property revenue consists of MH and RV site rent, and miscellaneous other property revenues. The 7.4% growth in income from real property is primarily due to increased revenue from our MH and RV portfolio of $4.9 million due to the increased number of occupied home sites and the increase to our weighted average rental rate of 3.1%. Additionally, an increase in transient RV revenue of $0.4 million, and an increase in other miscellaneous property revenue of $0.6 million.

Property operating expenses increased approximately $0.9 million, or 3.7%, compared to 2014. Of that increase, utility expenses increased $0.7 million primarily due to increased electric, Internet and rubbish removal. Legal, taxes and insurance expenses increased $0.2 million, primarily due to an increase in property and casualty insurance. Supplies and repair expenses increased $0.5 million primarily due to increases in tree trimming and community maintenance expenses.

HOME SALES AND RENTALS

We acquire pre-owned and repossessed manufactured homes generally located within our communities from lenders and dealers at substantial discounts. We lease or sell these value priced homes to current and prospective residents. We also purchase new homes to lease and sell to current and prospective residents.

The following table reflects certain financial and other information for our Rental Program as of and for the three months ended September 30, 2015 and 2014 (in thousands, except for statistical information):

	Three Months Ended September 30,

Number of sold rental homes	223		208		15			7.2	%
Weighted average monthly rental rate, end of period	$	843	$	816	$	27		3.3	%

⁽¹⁾ The renter’s monthly payment includes the site rent and an amount attributable to the leasing of the home. The site rent is reflected in the Real Property Operations segment. For purposes of management analysis, the site rent is included in the Rental Program revenue to evaluate the incremental revenue gains associated with implementation of the Rental Program, and assess the overall growth and performance of the Rental Program and financial impact to our operations.

The 20.1% growth in NOI is primarily a result of the increased number of residents participating in the Rental Program and from increased monthly rental rates as indicated in the table above.

The increase in operating and maintenance expenses of $0.8 million was primarily a result of increased taxes and insurance expense of $0.3 million due to property and casualty insurance and personal property tax increases on the homes. Also, commissions expense increased by $0.2 million and expenses related to refurbishment of the home after a renter move-out increased by $0.3 million.

Ancillary revenues, net increased primarily due to increased golf course income and increased ticket and merchandise income.

Interest income increased primarily due to an increase in interest income on collateralized receivables of $0.4 million.

Brokerage commissions and other revenues increased primarily due to the increase in brokerage commissions due to an increase in the number of brokered homes sold.

Real property general and administrative expenses increased primarily due to increased salaries, wages and related taxes of $0.8 million, increased employee benefits and incentives of $1.6 million, increased deferred compensation expense of $0.7 million, and increased software support and licensing fees, legal, workers compensation, consulting and property and casualty insurance of $0.7 million.

Home sales and rentals general and administrative expenses increased primarily due to increased salaries, wages and related taxes of $0.8 million, increased commissions on home sales of $0.3 million, increased employee benefits and incentives of $0.1 million, and increased advertising and utility expense of $0.2 million.

Transaction costs decreased as a result of lower acquisition costs during the third quarter of 2015 compared to higher diligence costs related to the pending Green Courte acquisition during the third quarter of 2014 (see Notes 2 in our Consolidated Financial Statements).

Depreciation and amortization expenses increased as a result of additional depreciation and amortization of $11.7 million primarily related to our newly acquired properties, $1.5 million related to depreciation on investment property for use in our Rental Program, and $1.3 million related to the amortization of in-place leases and promotions.

Asset impairment charge decreased as a result of no impairments in 2015.

Interest expense on debt, including interest on mandatorily redeemable preferred OP units, increased primarily as a result of a $7.0 million increase in mortgage interest due to the acquisition of the Green Courte and Berger properties, an increase of $3.5 million of interest on miscellaneous other long term debt, a $0.4 million increase in interest expense associated with our secured borrowing arrangements, and an increase of $0.4 million of interest on our line of credit, partially offset by $2.5 million of mark to market adjustments on assumed debt.

⁽¹⁾    Occupied sites and occupancy % include MH and annual RV sites, and exclude transient RV sites, which are included in total developed sites.

⁽²⁾ Occupancy % excludes recently completed but vacant expansion sites.

⁽³⁾  Weighted average rent pertains to annual RV sites and excludes transient RV sites.

The 9.2% growth in NOI is primarily due to increased revenues of $17.2 million partially offset by an increase in expenses of $2.6 million.

Income from real property revenue consists of MH and RV site rent, and miscellaneous other property revenues.  The 7.5% growth in income from real property is primarily due to increased revenue from our MH and RV portfolio of $14.1 million as a result of the increased number of occupied home sites and the increase to our weighted average rental rate of 3.1%. Additionally, transient RV revenue increased $1.6 million and other revenues increased by $1.5 million primarily due to an increase in month to month fees, trash income, electric and gas income, cable television royalties, application fees, and other charges and fee revenue.

Property operating expenses increased $2.6 million, or 3.6% compared to 2014. Of that increase, salaries and wages, workers compensation costs and health insurance costs increased $1.0 million, legal, taxes and insurance expenses increased $0.6 million primarily due to increased property and casualty insurance, utilities increased $0.4 million primarily due to electric costs, supplies and repair increased $0.3 million primarily due to tree trimming, and other miscellaneous expenses increased $0.3 million primarily due to increases in credit card processing charges, corporate advertising and meeting expenses.

Weighted average monthly rental rate, end of period	$	843	$	816	$	27		3.3	%

⁽¹⁾ The renter’s monthly payment includes the site rent and an amount attributable to the leasing of the home. The site rent is reflected in the Real Property Operations segment. For purposes of management analysis, the site rent is included in the Rental Program revenue to evaluate the incremental revenue gains associated with implementation of the Rental Program, and assess the overall growth and performance of the Rental Program and financial impact to our operations.

The 19.8% growth in NOI is primarily a result of the increased number of residents participating in the Rental Program and from increased monthly rental rates as indicated in the table above.

The increase in operating and maintenance expenses of $1.4 million was primarily a result of a $0.5 million increase in commissions expense due to the increased number of new leases and taxes and insurance expense of $0.7 million due to increases in property and casualty insurance, personal property taxes on the homes and use tax expense, and repairs and refurbishment increased $0.2 million primarily due to expenses related to the refurbishment of the home after a renter move-out.

FUNDS FROM OPERATIONS

We provide information regarding FFO as a supplemental measure of financial and operational performance. FFO is defined by NAREIT as net income (loss) (computed in accordance with GAAP), excluding extraordinary items (as defined under GAAP), and gain (loss) on sales of depreciable operating property, plus real estate related depreciation and amortization (excluding amortization of financing costs), and after adjustments for unconsolidated partnerships and joint ventures. Due to the variety among owners of identical assets in similar condition (based on historical cost accounting and useful life estimates), we believe excluding gains and losses related to sales of previously depreciated operating real estate assets, impairment and excluding real estate asset depreciation and amortization, provides a better indicator of our operating performance. FFO is a useful supplemental measure of our operating performance because it reflects the impact to operations from trends in occupancy rates, rental rates, and operating costs, providing perspective not readily apparent from net income (loss). Management believes that the use of FFO has been beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful. Management, the investment community, and banking institutions routinely use FFO, together with other measures, to measure operating performance in our industry. Further, management uses FFO for planning and forecasting future periods.

Because FFO excludes significant economic components of net income (loss) including depreciation and amortization, FFO should be used as an adjunct to net income (loss) and not as an alternative to net income (loss). The principal limitation of FFO is that it does not represent cash flow from operations as defined by GAAP and is a supplemental measure of performance that does not replace net income (loss) as a measure of performance or net cash provided by operating activities as a measure of liquidity. In addition, FFO is not intended as a measure of a REIT’s ability to meet debt principal repayments and other cash requirements, nor as a measure of working capital. FFO only provides investors with an additional performance measure. FFO is compiled in accordance with its interpretation of standards established by NAREIT, which may not be comparable to FFO reported by other REITs that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently.

LIQUIDITY AND CAPITAL RESOURCES

Our principal liquidity demands have historically been, and are expected to continue to be, distributions to our stockholders and the unit holders of the Operating Partnership, capital improvement of properties, the purchase of new and pre-owned homes, property acquisitions, development and expansion of properties, and debt repayment.

Subject to market conditions, we intend to continue to look for opportunities to expand our development pipeline and acquire existing communities. We also intend to continue to strengthen our capital and liquidity positions by continuing to focus on our core fundamentals, which are generating positive cash flows from operations, maintaining appropriate debt levels and leverage ratios, and controlling overhead costs. We intend to meet our liquidity requirements through available cash balances, cash flows generated from operations, draws on our unsecured credit facility, and the use of debt and equity offerings under our automatic shelf registration statement.

During the nine months ended September 30, 2015, we acquired 34 MH communities and four RV communities with approximately 15,600 sites. We also disposed of four MH communities with approximately 1,700 sites. See Note 2 to our Consolidated Financial Statements for details on the 2015 acquisitions and dispositions and Note 8 to our Consolidated Financial Statements for related debt transactions.

We will continue to evaluate acquisition opportunities that meet our criteria for acquisition. Should additional investment opportunities arise in 2015, we intend to finance the acquisitions through available cash, secured financing, draws on our credit facilities, the assumption of existing debt on the properties, and the issuance of certain equity securities.

During the nine months ended September 30, 2015, we invested $38.9 million in the acquisition of homes intended for the Rental Program net of proceeds from third-party financing from home sales. Expenditures for 2015 will depend upon the condition of the markets for repossessions and new home sales, as well as rental homes. We finance new home purchases with a $12.0 million manufactured home floor plan facility. Our ability to purchase homes for sale or rent may be limited by cash received from third-party financing of our home sales, available manufactured home floor plan financing and working capital available on our secured lines of credit.

Our cash flow activities are summarized as follows (in thousands):

	Nine Months Ended September 30,
	2015			2014
Net Cash Provided by Operating Activities	$	146,778		$	109,259
Net Cash Used for Investing Activities	$	(403,205	)	$	(248,622	)
Net Cash Provided by Financing Activities	$	196,885		$	393,762

Cash and cash equivalents decreased by $(59.5) million from $83.5 million as of December 31, 2014, to $23.9 million as of September 30, 2015.

Operating Activities

Net cash provided by operating activities increased by $37.5 million from $109.3 million for the nine months ended September 30, 2014 to $146.8 million for the nine months ended September 30, 2015.

Our net cash flows provided by operating activities from continuing operations may be adversely impacted by, among other things: (a) the market and economic conditions in our current markets generally, and specifically in metropolitan areas of our current markets; (b) lower occupancy and rental rates of our properties; (c) increased operating costs, such as wage and benefit costs, insurance premiums, real estate taxes and utilities, that cannot be passed on to our tenants; (d) decreased sales of manufactured homes; and (e) current volatility in economic conditions and the financial markets.  See “Risk Factors” in Part I, Item 1A of our 2014 Annual Report.

Investing Activities

Net cash used for investing activities was $403.2 million for the nine months ended September 30, 2015, compared to $248.6 million for the nine months ended September 30, 2014. The increase is primarily due to increased cash used for the continued

44

SUN COMMUNITIES, INC.

acquisition of properties, as well as recurring investment in existing properties. These items are partially offset by decreased cash proceeds related to the disposition of properties, and decreased payments for deposits on acquisitions.

Financing Activities

Net cash provided by financing activities was $196.9 million for the nine months ended September 30, 2015, compared to $393.8 million for the nine months ended September 30, 2014. The decrease is primarily due to a significant decrease in the Company's equity offerings in 2015 as compared to the Green Courte equity offerings in 2014. This reduction in proceeds is partially offset by decreased net activity associated with our lines of credit and other debt.

Financial Flexibility

In August, 2015, we amended and restated our senior revolving credit facility with Citibank, N.A. and certain other lenders in the amount of $450.0 million, comprised of a $392.0 million revolving loan and $58.0 million term loan (the "Facility"). The Facility has a four year term ending August 19, 2019, which can be extended for two additional six-month periods at our option, subject to the satisfaction of certain conditions as defined in the credit agreement. The credit agreement also provides for, subject to the satisfaction of certain conditions, additional commitments in an amount not to exceed $300.0 million. If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the Facility may be increased up to $750.0 million. The Facility bears interest at a floating rate based on the Eurodollar rate plus a margin that is determined based on our leverage ratio calculated in accordance with the credit agreement, which can range from 1.40% to 2.25% for the revolving loan and 1.35% to 2.20% for the term loan. As of September 30, 2015, the margin on our leverage ratio was 1.45% and 1.40% on the revolving and term loans, respectively. We had$142.0 million on the revolving loan and $25.0 million on the term loan totaling $167.0 million in borrowings as of September 30, 2015, with a weighted average interest rate of 1.66%. As of December 31, 2014 there was no amount outstanding under our previous credit Facility.

The Facility provides us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under our line of credit, but it does reduce the borrowing amount available. At September 30, 2015 and December 31, 2014, approximately $3.4 million and $3.2 million of availability was used to back standby letters of credit.

Pursuant to the terms of the Facility, we are subject to various financial and other covenants. We are currently in compliance with these covenants. The most restrictive financial covenants for the Facility are as follows:

Covenant	Must Be	As of September 30, 2015
Maximum Leverage Ratio	<65.0%	42.7%
Minimum Fixed Charge Coverage Ratio	>1.40	2.48
Minimum Tangible Net Worth	1,736,435	$2,209,239
Maximum Dividend Payout Ratio	<95.0%	77.3%

Market and Economic Conditions

U.S. rate environment, monetary policy change in China, Japan and the Euro area, falling oil prices, and turmoil in emerging markets are factors that are influencing financial markets in 2015. Questions still exist on whether the U.S. economy will sustain the growth indicators it has reported and whether or when the U.S. Federal Reserve will increase its benchmark rate for the first time in 10 years, as well as how Japan and the Eurozone will recover amidst easing monetary policy. The possible negative effects on the world economy of the recent Chinese stock market decline and additional global turmoil keep economic outlooks tempered. While the U.S. economy looks poised for self-sustaining growth, the global economy is seeing modest improvement led by developed countries. Continued economic uncertainty, both nationally and internationally, causes increased volatility in investor confidence thereby creating similar volatility in the availability of both debt and equity capital. If such volatility is experienced in future periods, our industry, business and results of operations may be adversely impacted.

We anticipate meeting our long-term liquidity requirements, such as scheduled debt maturities, large property acquisitions, and Operating Partnership unit redemptions through the issuance of certain debt or equity securities and/or the collateralization of our properties. At September 30, 2015, we had 81 unencumbered properties with an estimated market value of $945.8 million. Seventy-seven of these unencumbered properties support the borrowing base for our $450.0 million unsecured line of credit.  From time to time, we may also issue shares of our capital stock, issue equity units in our Operating Partnership, obtain debt financing, or sell selected assets. Our ability to finance our long-term liquidity requirements in such a manner will be affected by numerous

45

SUN COMMUNITIES, INC.

economic factors affecting the manufactured housing community industry at the time, including the availability and cost of mortgage debt, our financial condition, the operating history of the properties, the state of the debt and equity markets, and the general national, regional, and local economic conditions. When it becomes necessary for us to approach the credit markets, the volatility in those markets could make borrowing more difficult to secure, more expensive, or effectively unavailable. See “Risk Factors” in Part I, Item 1A of our 2014 Annual Report. If we are unable to obtain additional debt or equity financing on acceptable terms, our business, results of operations and financial condition would be adversely impacted.

There have been no material effects of damage to our communities as a result of Hurricane Joaquin in October 2015.

As of September 30, 2015, our net debt to enterprise value approximated 37.9%(assuming conversion of all common OP units, Series A-1 preferred OP units, Series A-3 preferred OP units, Series A-4 preferred OP units, and Series C units to shares of common stock). Our debt has a weighted average maturity of approximately 8.1 years and a weighted average interest rate of 5.1%.

Capital expenditures for the nine months ended September 30, 2015 and 2014 included recurring capital expenditures of $13.6 million and $10.8 million, respectively. We are committed to the continued upkeep of our properties and therefore do not expect a decline in our recurring capital expenditures during 2015.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our principal market risk exposure is interest rate risk. We mitigate this risk by maintaining prudent amounts of leverage, minimizing capital costs, and interest expense while continuously evaluating all available debt and equity resources and following established risk management policies and procedures, which include the periodic use of derivatives. Our primary strategy in entering into derivative contracts is to minimize the variability that interest rate changes could have on our future cash flows. We generally employ derivative instruments that effectively convert a portion of our variable rate debt to fixed rate debt. We do not enter into derivative instruments for speculative purposes.

We have two interest rate cap agreements with a total notional amount of $160.1 million as of September 30, 2015. The first interest rate cap agreement has a cap rate of 9.00%, a notional amount of $150.1 million and a termination date of April 2018. The second interest rate cap agreement has a cap rate of 11.02%, a notional amount of $10.0 million and a termination date of October 2016.

Our remaining variable rate debt totals $325.9 million and $161.5 million as of September 30, 2015 and 2014, respectively, and bears interest at Prime or various LIBOR rates. If Prime or LIBOR increased or decreased by 1.0%, we believe our interest expense would have increased or decreased by approximately $2.2 million and $3.2 million as of September 30, 2015 and 2014, respectively, based on the $216.6 million and $316.4 million average balances outstanding under our variable rate debt facilities, respectively.

ITEM 4.  CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer, Gary A. Shiffman, and Chief Financial Officer, Karen J. Dearing, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this quarterly report, pursuant to Rule 13a-15 of the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report were effective to ensure that information we are required to disclose in our filings with the SEC under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and to ensure that information we are required to disclose in the reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in internal control over financial reporting

There have been no changes in our internal control over financial reporting during the quarterly period ended September 30, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

See Note 17 included in Part I, Item 1, "Notes to Unaudited Consolidated Financial Statements", within this quarterly report on Form 10-Q.

ITEM 1A.  RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the factors in Part 1, Item 1A., "Risk Factors", in our 2014 Annual Report, which could materially affect our business, financial condition or future results. There have been no material changes to the disclosure on these matters set forth in the 2014 Annual Report.

ITEM 2.  UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Issuer Purchases of Equity Securities

In November 2004, our Board of Directors authorized us to repurchase up to 1,000,000 shares of our common stock.  We have 400,000 common shares remaining in the repurchase program.  No common shares were repurchased under this buyback program during the nine months ended September 30, 2015.  There is no expiration date specified for the buyback program.

On July 29, 2015, we entered into a Repurchase Agreement with certain holders of shares of our Series A-4 Preferred Stock under which, at the holders’ election, we were obligated to repurchase up to 5,926,322 shares of Series A-4 Preferred Stock from the Series A-4 Preferred Stock holders. The price paid consisted of a price per share of $30.90 plus $0.18 for accrued and unpaid distributions from and including June 30, 2015 to, but not including, August 10, 2015. The sale right of the holders of the Series A-4 Preferred Shares to sell such shares under the Repurchase Agreement expired on August 10, 2015. We announced the Repurchase Agreement in a press release dated July 30, 2015 and a Form 8-K filed with the SEC on July 30, 2015 and announced the expiration the sale right associated with the Repurchase Agreement in a Form 8-K filed with the SEC on August 14, 2015. See Note 9 in our Consolidated Financial Statements.

During the quarter ended September 30, 2015, we repurchased shares of Series A-4 Preferred Stock in the following amounts at the following average prices:

Period	Total number of shares purchased	Average price paid per share		Total number of shares purchased as part of publicly announced plans or programs	Maximum number of shares that may yet be purchased under the plans or programs
July 1 - July 31	—	$	—	—	—
August 1 - August 31	4,066,586	$	31.08	4,066,586	—
September 1 - September 30	—	$	—	—	—
Total	4,066,586	$	31.08	4,066.586	—

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

Sun Communities, Inc., a Maryland corporation, and all wholly-owned or majority-owned and controlled subsidiaries, including Sun Communities Operating Limited Partnership (the “Operating Partnership”), SunChamp LLC (“SunChamp”), and Sun Home Services, Inc. (“SHS”) are referred to herein as the "Company," "us," "we," and "our".

We follow accounting standards set by the Financial Accounting Standards Board ("FASB"). FASB sets generally accepted accounting principles ("GAAP"), which we follow to ensure that we consistently report our financial condition, results of operations, and cash flows. References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification.

These unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information and in accordance with GAAP. Pursuant to the SEC rules and regulations we present interim disclosures and certain information and footnote disclosures as required. Accordingly, the unaudited Consolidated Financial Statements do not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying unaudited Consolidated Financial Statements reflect, in the opinion of management, all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of the interim financial statements. All intercompany transactions have been eliminated in consolidation. Certain reclassifications have been made to prior periods' financial statements in order to conform to current period presentation.

The results of operations for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2014 as filed with the SEC on March 2, 2015 (the “2014 Annual Report”). These statements have been prepared on a basis that is substantially consistent with the accounting principles applied in our 2014 Annual Report.

Derivative Instruments And Hedging Activities

Derivative Instruments and Hedging Activities

Our objective in using interest rate derivatives is to manage exposure to interest rate movements thereby minimizing the effect of interest rate changes and the effect it could have on future cash flows. Interest rate caps are used to accomplish this objective. We do not enter into derivative instruments for speculative purposes nor do we have any swaps in a hedging arrangement.

The following table provides the terms of our interestrate derivative contracts that were in effect as of September 30, 2015:

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent Accounting Pronouncements

In April 2015, the FASB issued ASU 2015-03 "Interest - Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03"). This amendment requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. In August 2015, the FASB issued ASU 2015-15 "Interest - Imputation of Interest (Subtopic 835-30) Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements" ("ASU 2015-15"). This amendment provides additional guidance within ASU 2015-03 for debt issuance costs related to line of credit arrangements. These amendments are effective for fiscal years beginning after December 15, 2015, and interim periods within those years, with early adoption permitted. Entities should apply the amendments retrospectively. We are currently evaluating the potential impact these amendments will have on our Consolidated Financial Statements.

In February 2015, the FASB issued ASU No. 2015-02 "Consolidation (Topic 810) Amendments to the Consolidation Analysis" ("ASU 2015-02"). This amendment eliminates the deferral of FAS 167, which has allowed entities with interests in certain investment funds to follow the previous consolidation guidance in FIN 46(R), and makes other changes to both the variable interest model and the voting model. While the guidance is aimed at asset managers, it will affect all reporting entities that have variable interests in other legal entities (e.g., limited partnerships, similar entities and certain corporations). In some cases, consolidation conclusions will change. In other cases, reporting entities will need to provide additional disclosures about entities that currently aren’t considered VIEs but will be considered VIEs under the new guidance provided they have a variable interest in those VIEs. These amendments are effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. Entities may apply the amendments using either a modified retrospective approach or retrospectively. We are currently evaluating the potential impact this amendment will have on our Consolidated Financial Statements.

In August 2014, the FASB issued ASU 2014-15 "Disclosure of Uncertainties About an Entity's Ability to Continue as a Going Concern" ("ASU 2014-15"). This amendment requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date the financial statements are issued and provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. Certain disclosures will be required if conditions give rise to substantial doubt about an entity's ability to continue as a going concern. This amendment applies to all entities and are effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. We are currently evaluating the potential impact this amendment will have on our quarterly reporting process.

In May 2014, the FASB issued ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"). The objective of this amendment is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying this amendment, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. This amendment applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC. This amendment is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period; early adoption is not permitted. An entity should apply the amendments using either the full retrospective approach or retrospectively with a cumulative effect of initially applying the amendments recognized at the date of initial application. We are currently evaluating the methods of adoption and the impact that the adoption of ASU 2014-09 may have on our Consolidated Financial Statements.

Stockholders' Equity Note [Abstract]

Equity Transactions

Equity and Mezzanine Securities

At the Company's Annual Meeting of Stockholders on July 20, 2015, the stockholders approved Articles of Amendment to our Amended and Restated Articles of Incorporation, as amended and supplemented, under which the number of authorized shares of our common stock, $0.01 par value per share, was increased from 90,000,000 to 180,000,000 and the number of our preferred stock, $0.01 par value per share, was increased from 10,000,000 to 20,000,000.

In July 2015, the Company entered into a repurchase agreement with certain holders of shares of Series A-4 Preferred Stock under which, at the holders’ election, the Company was obligated to repurchase up to 5,926,322 shares of the Series A-4 Preferred Stock from the holders of those shares. There were 6,364,770 shares of Series A-4 preferred shares issued and outstanding at the time of the repurchase agreement, and 438,448 shares of Series A-4 Preferred Stock were not subject to the repurchase agreement. Each holder of shares of Series A-4 Preferred Stock subject to the repurchase agreement could have elected to sell its shares of Series A-4 Preferred Stock to the Company. The purchase price was $31.08 per share, which consists of a price per share of $30.90 plus $0.18 for accrued and unpaid distributions from and including June 30, 2015 to, but not including, August 10, 2015. Each share of Series A-4 Preferred Stock had a liquidation preference of $25.00 per share, and was convertible into approximately 0.4444 shares of the Company’s common stock. Pursuant to the repurchase agreement, the Company repurchased 4,066,586 shares of the Series A-4 Preferred Stock. There are 2,298,184 shares of Series A-4 Preferred Stock issued and outstanding as of September 30, 2015.

In June 2015, we issued to GCP Fund III Ancillary Holding, LLC (i) 25,664 shares of common stock at an issuance price of $50.00 per share or $1,283,200 in the aggregate, and (ii) 34,219 shares of Series A-4 Preferred Stock at an issuance price of $25.00 per share, or $855,475 in the aggregate. All of these common shares and preferred shares were issued for cash consideration pursuant to the terms of a Subscription Agreement, dated July 30, 2014, as amended, among the Company, Green Court Real Estate Partners III, LLC, and certain other parties. The parties have agreed that no additional securities are issuable under the Subscription Agreement.

Also in June 2015, we entered into an At the Market Offering Sales Agreement (the "Sales Agreement") with BMO Capital Markets Corp., Merrill Lynch, Pierce, Fenner and Smith Incorporated and Citigroup Global Markets Inc. (collectively, the "Sales Agents"). Pursuant to the Sales Agreement, we may offer and sell shares of our common stock, having an aggregate offering price of up to $250.0 million, from time to time through the Sales Agents. Each Sales Agent is entitled to compensation in an agreed amount not to exceed 2.0% of the gross sales price per share for any shares sold through it from time to time under the Sales Agreement. Concurrently, the At the Market Offering Sales Agreement dated May 10, 2012, as amended among the Company, the Partnership, BMO Capital Markets Corp. and Liquidnet, Inc., was terminated. Prior to the termination of the At the Market Offering Sales Agreement dated May 10, 2012, during the first quarter of 2015, 342,011 shares of common stock were issued at the prevailing market price of our common stock at the time of each sale with a weighted average sale price of $63.94, and we received net proceeds of approximately $21.5 million.

During the third quarter of 2015, under the June 2015 Sales Agreement, we sold 608,100 common shares under the Sales Agreement, at an average sales price of $68.00 for net proceeds of $40.8 million.

During the second quarter of 2015, under the June 2015 Sales Agreement, we sold 26,200 common shares under the Sales Agreement, at an average sales price of $65.15 for net proceeds of $1.7 million.

In April 2015, in connection with the Berger acquisition, we issued 371,808 common OP units at an issuance price of $61.00 per share and 340,206 newly created Series C preferred OP units at an issuance price of $100.00 per share. The Series C preferred OP unit holders receive a preferred return of 4.0% per year from the closing until the second anniversary of the date of issuance, 4.5% per year during the following three years, and 5.0% per year thereafter. At the holder’s option, each Series C preferred OP unit will be exchangeable into 1.11 shares of the Company’s common stock and holders of Series C preferred OP units do not have any voting or consent rights.

In January 2015, in connection with the Green Courte second closing, we issued 4,377,073 shares of common stock at an issuance price of $50.00 per share and 5,847,234 shares of Series A-4 Preferred Stock at an issuance price of $25.00 per share. The Series A-4 Preferred Stock stockholders receive a preferred return of 6.5%. In addition, one of the Green Courte Partners funds purchased 150,000 shares of our common stock and 200,000 Series A-4 preferred OP units for an aggregate purchase price of $12.5 million. As noted above, in July 2015, the Company repurchased 4,066,586 shares of the Series A-4 Preferred Stock.

If certain change of control transactions occur or if our common stock ceases to be listed or quoted on an exchange or quotation system, then at any time after November 26, 2019, we or the holders of shares of Series A-4 Preferred Stock and Series A-4 preferred OP units may cause all or any of those shares or units to be redeemed for cash at a redemption price equal to the sum of (i) the greater of (x) the amount that the redeemed shares of Series A-4 Preferred Stock and Series A-4 preferred OP units would have received in such transaction if they had been converted into shares of our common stock immediately prior to such transaction, or (y) $25.00 per share, plus (ii) any accrued and unpaid distributions thereon to, but not including, the redemption date. The Series A-4 preferred OP units are inclusive of its pro-rata share of net income of $0.3 million and distributions of $1.0 million for the nine months ended September 30, 2015.

In November 2004, our Board of Directors authorized us to repurchase up to 1,000,000 shares of our common stock. We have 400,000 common shares remaining in the repurchase program. No common shares were repurchased under this buyback program during the nine months ended September 30, 2015 or 2014. There is no expiration date specified for the buyback program.

Common OP unit holders can convert their common OP units into an equivalent number of shares of common stock at any time. During the nine months ended September 30, 2015, there were 99,404 common OP units converted to shares of common stock. No such units were converted during the nine months ended September 30, 2014.

Subject to certain limitations, Series A-1 preferred OP unit holders may convert their Series A-1 preferred OP units to shares of our common stock at any time. During the nine months ended September 30, 2015 and 2014, holders of Series A-1 preferred OP units converted 38,817 units into 102,301 shares of common stock, and 18,773 units into 45,785 shares of common stock, respectively.

Subject to certain limitations, Series A-4 preferred OP unit holders may convert their Series A-4 preferred OP units to shares of our common stock at any time. During the nine months ended September 30, 2015, holders of Series A-4 preferred OP units converted 109,414 units into 48,627 shares of common stock. No such units were converted during the nine months ended September 30, 2014.

Cash distributions of $0.65 per share were declared for the quarter ended September 30, 2015. On October 16, 2015, cash payments of approximately $37.3 million for aggregate distributions were made to common stockholders, common OP unit holders and restricted stockholders of record as of September 30, 2015.

Share-based Compensation [Abstract]

Share-Based Compensation

Share-Based Compensation

At the Annual Meeting of Stockholders held on July 20, 2015, the stockholders approved Sun Communities, Inc. Equity Incentive Plan ("2015 Equity Plan"). The 2015 Equity Plan had been adopted by the Board and was effective upon approval by our stockholders. The 2015 Equity Plan replaced the Sun Communities, Inc. Equity Incentive Plan adopted in 2009. The maximum number of shares of common stock that may be issued under the 2015 Equity Plan is 1,750,000 shares of our common stock.

In September 2015, we granted 4,500 shares of restricted stock to key employees under our 2015 Equity Plan. The shares had a fair value of $67.29 per share and will vest as follows: September 29, 2018: 35%; September 29, 2019: 35%; September 29, 2020: 20%; September 29, 2021: 5%; and September 29, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In July 2015, we granted 20,000 shares of restricted stock to an executive officer under our Sun Communities, Inc. Equity Incentive Plan ("2009 Equity Plan"). The shares had a fair value of $67.57 per share and will vest as follows: July 16, 2018: 35%; July 19, 2019: 35%; July 16, 2020: 20%; July 16, 2021: 5%; and July 16, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In May 2015, we granted 25,000 shares of restricted stock to an executive officer under our 2009 Equity Plan. The shares had a fair value of $62.94 per share and will vest as follows: May 19, 2018: 35%; May 19, 2019: 35%; May 19, 2020: 20%; May 19, 2021: 5%; and May 19, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In April 2015, we granted 145,000 shares of restricted stock to our executive officers under our 2009 Equity Plan. The shares had a fair value of $63.81 per share. Half of the shares will vest as follows: April 14, 2018: 20%; April 14, 2019: 30%; April 14, 2020: 35%; April 14, 2021: 10%; and April 14, 2022: 5%. The remaining 72,500 shares are subject to market and performance conditions which vest over time through April 2020. Share-based compensation for restricted stock awards with performance conditions is measured based on an estimate of shares expected to vest. We estimate the fair value of share-based compensation for restricted stock with market conditions using a Monte Carlo simulation.

In February 2015, we granted 19,800 shares of restricted stock to our non-employee directors under our First Amended and Restated 2004 Non-Employee Director Option Plan. The awards vest on February 11, 2018, and had a fair value of $65.87 per share. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In January 2015, we granted 1,000 shares of restricted stock to key employees under our 2009 Equity Plan. The shares had a fair value of $65.48 per share and will vest as follows: January 8, 2018: 35%; January 8, 2019: 35%; January 8, 2020: 20%;

January 8, 2021: 5%; and January 8, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

During the nine months ended September 30, 2015 and 2014, 4,084 and 4,904 shares of common stock, respectively, were issued in connection with the exercise of stock options, and the net proceeds received during both periods was $0.1 million.

The vesting requirements for 85,958 restricted shares granted to our executives and employees were satisfied during the nine months ended September 30, 2015.

Collateralized Receivables and Transfers of Financial Assets

Transfers and Servicing [Abstract]

Transfers Of Financial Assets

Transfers of Financial Assets

We completed various transactions with an unrelated entity involving our notes receivable under which we received cash proceeds in exchange for relinquishing our right, title, and interest in certain notes receivable. We have no further obligations or rights with respect to the control, management, administration, servicing, or collection of the installment notes receivable. However, we are subject to certain recourse provisions requiring us to purchase the underlying homes collateralizing such notes, in the event of a note default and subsequent repossession of the home by the unrelated entity. The recourse provisions are considered to be a form of continuing involvement, and therefore these transferred loans did not meet the requirements for sale accounting. We continue to recognize these transferred loans on our balance sheet and refer to them as collateralized receivables. The proceeds from the transfer have been recognized as a secured borrowing.

In the event of a note default and subsequent repossession of a manufactured home by the unrelated entity, the terms of the agreement require us to repurchase the manufactured home. Default is defined as the failure to repay the installment note receivable according to contractual terms. The repurchase price is calculated as a percentage of the outstanding principal balance of the collateralized receivable, plus any outstanding late fees, accrued interest, legal fees, and escrow advances associated with the installment note receivable.  The percentage used to determine the repurchase price of the outstanding principal balance on the installment note receivable is based on the number of payments made on the note. In general, the repurchase price is determined as follows:

Number of Payments	Repurchase Percentage
Fewer than or equal to 15	100	%
Greater than 15 but less than 64	90	%
Equal to or greater than 64 but less than 120	65	%
120 or more	50	%

The transferred assets have been classified as Collateralized receivables, net and the cash proceeds received from these transactions have been classified as a Secured borrowing within the Consolidated Balance Sheets. The balance of the collateralized receivables was $138.2 million (net of allowance of $0.6 million) and $123.0 million (net of allowance of $0.7 million) as of September 30, 2015 and December 31, 2014, respectively. The receivables have a weighted average interest rate and maturity of 10.2% and 15.2 years as of September 30, 2015, and 10.4% and 14.6 years as of December 31, 2014.

The outstanding balance on the secured borrowing was $138.9 million and $123.7 million as of September 30, 2015 and December 31, 2014, respectively.

The collateralized receivables earn interest income, and the secured borrowings accrue interest expense at the same interest rates. The amount of interest income and expense recognized was $3.3 million and $3.0 million, and $9.6 million and $8.6 million for the three and nine months endedSeptember 30, 2015 and 2014, respectively.  

The balances of the collateralized receivables and secured borrowings fluctuate. The balances increase as additional notes receivable are transferred and exchanged for cash proceeds. The balances are reduced as the related collateralized receivables are collected from the customers, or as the underlying collateral is repurchased. The change in the aggregate gross principal balance of the collateralized receivables is as follows (in thousands):

	Nine Months Ended

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value Of Financial Instruments

Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts and notes receivable, accounts payable, derivative instruments, and debt.

ASC Topic 820 "Fair Value Measurements and Disclosures" ("ASC 820"), requires disclosure about how fair value is determined for assets and liabilities and establishes a hierarchy under which these assets and liabilities must be grouped, based on significant levels of observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's market assumption. This hierarchy requires the use of observable market data when available. These two types of inputs have created the following fair value hierarchy:

Level 1—Quoted unadjusted prices for identical instruments in active markets.

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.

Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The following methods and assumptions were used in order to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Derivative Instruments

The derivative instruments held by us are interest rate cap agreements for which quoted market prices are indirectly available. For those derivatives, we use model-derived valuations in which all significant inputs and significant value drivers are observable in active markets provided by brokers or dealers to determine the fair value of derivative instruments on a recurring basis (Level 2). See Note 14 for Derivative Instruments.

Installment Notes Receivable on Manufactured Homes

The net carrying value of the installment notes receivable on manufactured homes estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). See Note 4 for Installment Notes Receivable.

Long-Term Debt and Lines of Credit

The fair value of long-term debt (excluding the secured borrowing) is based on the estimates of management and on rates currently quoted, rates currently prevailing for comparable loans, and instruments of comparable maturities (Level 2). See Note 8 for Long-Term Debt and Lines of Credit.

Collateralized Receivables and Secured Borrowings

The fair value of these financial instruments offset each other as our collateralized receivables represent a transfer of financial assets and the cash proceeds received from these transactions have been classified as a secured borrowing on the Consolidated Balance Sheets. The net carrying value of the collateralized receivables estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). See Note 3 for Collateralized Receivables and Secured Borrowing.

Other Financial Instruments

The carrying values of cash and cash equivalents, accounts receivable, and accounts payable approximate their fair market values due to the short-term nature of these instruments.

The table below sets forth our financial assets and liabilities that require disclosure of their fair values on a recurring basis and presents the carrying values and fair values as of September 30, 2015 and December 31, 2014 that were measured using the valuation techniques described above. The table excludes other financial instruments such as cash and cash equivalents, accounts receivable, and accounts payable because the carrying values associated with these instruments approximate fair value since their maturities are less than one year.

	September 30, 2015				December 31, 2014
Financial assets	Carrying Value		Fair Value		Carrying Value		Fair Value
Installment notes receivable on manufactured homes, net	$	22,375	$	22,375	$	25,884	$	25,884
Collateralized receivables, net	$	138,241	$	138,241	$	122,962	$	122,962
Financial liabilities
Debt	$	2,251,663	$	2,289,252	$	1,702,643	$	1,752,939
Secured borrowing	$	138,887	$	138,887	$	123,650	$	123,649
Lines of credit	$	167,000	$	167,000	$	5,794	$	5,794

The derivative instruments are the only financial liabilities that were required to be carried at fair value on the Consolidated Balance Sheets as of September 30, 2015 and December 31, 2014. We have no financial assets that are required to be carried at fair value.

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

We group our operating segments into reportable segments that provide similar products and services. Each operating segment has discrete financial information evaluated regularly by the Company's chief operating decision maker in evaluating and assessing performance. We have two reportable segments: (i) Real Property Operations and (ii) Home Sales and Rentals. The Real Property Operations segment owns, operates, and develops MH communities and RV communities and is in the business of acquiring, operating, and expanding MH and RV communities.  The Home Sales and Rentals segment offers manufactured home sales and leasing services to tenants and prospective tenants of our communities. 

Transactions between our segments are eliminated in consolidation.  Transient RV revenue is included in the Real Property Operations segment revenues and is expected to approximate $39.3 million annually. In 2015, we recognized 22.4%, 17.4% and 45.2% during the first, second and third quarters, respectively. We expect to recognize 15.0% during the fourth quarter of 2015. In 2014, transient revenue was $31.6 million. We recognized 25.3% in the first quarter, 18.3% in the second quarter, 43.3% in the third quarter, and 13.1% in the fourth quarter.

A presentation of segment financial information is summarized as follows (amounts in thousands):

Consolidated Variable Interest Entities

   Consolidated Variable Interest Entities

Variable interest entities ("VIEs") that are consolidated include Rudgate Village SPE, LLC, Rudgate Clinton SPE, LLC, Rudgate Clinton Estates SPE, LLC (the “Rudgate Borrowers”), and Wildwood Village Mobile Home Park ("Wildwood"). We evaluated our arrangements with these properties under the guidance set forth in FASB Accounting Standard Codification ("ASC") ASC Topic 810 "Consolidation". We concluded that the Rudgate Borrowers and Wildwood qualify as VIEs as we are the primary beneficiary and hold controlling financial interests in these entities due to our power to direct the activities that most significantly impact the economic performance of the entities, as well as our obligation to absorb the most significant losses and our rights to receive significant benefits from these entities. As such, the transactions and accounts of these VIEs are included in the accompanying Consolidated Financial Statements.

The following table summarizes the assets and liabilities included in our Consolidated Balance Sheets after appropriate eliminations have been made (in thousands):

	September 30, 2015			December 31, 2014

Noncontrolling interests	(1,336		)	(416		)
Total Liabilities and Stockholders' Equity	$	82,669		$	75,875

Investment property, net and other assets related to the consolidated VIEs comprised approximately 2.3% and 3.4% of our consolidated total assets at September 30, 2015 and December 31, 2014, respectively. Debt and other liabilities comprised approximately 2.9% and 3.8% of our consolidated total liabilities at September 30, 2015 and December 31, 2014, respectively. Noncontrolling interest related to the consolidated VIEs comprised less than 1.0% of our consolidated total equity at September 30, 2015 and December 31, 2014.

Investment in Affiliates

Origen Financial Services, LLC (“OFS LLC”)

At September 30, 2015 and December 31, 2014, we had a 22.9% ownership interest in OFS LLC, an entity formed to originate manufactured housing installment contracts. We have suspended equity accounting as the carrying value of our investment is zero.

Origen Financial, Inc. (“Origen”)

Through Sun OFI, LLC, a taxable REIT subsidiary, we own 5,000,000 shares of common stock in Origen, which approximates an ownership interest of 19%. We had suspended equity accounting for this investment as the carrying value of our investment was zero. In January 2015, Origen completed the sale of substantially all of its assets to an affiliate of GoldenTree Asset Management, LP and has announced its intention to dissolve and liquidate. During the second quarter of 2015, and as disclosed in a press release on March 30, 2015, Origen made an initial distribution of $1.50 per share to its stockholders of record as of April 13, 2015, retaining approximately $6.2 million for expected dissolution, wind down costs, expenses, and contingencies. Depending on the actual cost of estimated wind down expenses, Origen may make one or more additional interim distributions of excess cash to stockholders prior to completing liquidation. Upon completion of liquidation, Origen will distribute remaining cash, if any, to stockholders. During the second quarter of 2015, we received an initial distribution of $7.5 million from Origen.

Collateralized Term Loans

In August 2015, we entered into an agreement to borrow $87.0 million in mortgage debt that will be secured by five communities at an interest rate of 4.06% for a term of 25 years. This loan will close in two separate closings. In September 2015, we completed the first closing for $51.2 million secured by four communities and the second closing for $35.8 million is scheduled to close in December 2015.

In May 2015, we defeased a total of $70.6 million aggregate principal amount of collateralized term loans with an interest rate of 5.32% that were due to mature on July 1, 2016, releasing 10 communities. As a result of the transaction we recognized a loss on debt extinguishment of $2.8 million that is reflected in our Consolidated Statement of Operations.

In April 2015, in relation to the acquisition of the Berger properties (see Note 2), we assumed debt with a fair market value of $169.9 million on the communities with a weighted average interest rate of 5.17% and a weighted average remaining term of 6.3 years.

In March 2015, in relation to the acquisition of Meadowlands (see Note 2), we assumed a $6.3 million mortgage with an interest rate of 6.5% and a remaining term of 6.5 years. Also, in relation to this acquisition, we entered into a note payable with the seller for $2.4 million that bears no interest but is payable in three equal yearly installments beginning in March 2016.

In January 2015, in relation to the acquisition of the Green Courte properties (see Note 2), we refinanced approximately $90.8 million of mortgage debt on 10 of the communities (resulting in proceeds of $112.3 million) at a weighted average interest rate of 3.87% per annum and a weighted average term of 14.1 years. We also assumed approximately $201.4 million of mortgage debt at a weighted average interest rate of 5.74% and a weighted average remaining term of 6.3 years.

The collateralized term loans totaling $2.4 billion as of September 30, 2015, are secured by 171 properties comprised of 68,814 sites representing approximately $2.7 billion of net book value.

Secured Borrowing

See Note 3, "Collateralized Receivables and Transfers of Financial Assets", for additional information regarding our collateralized receivables and secured borrowing transactions.

Preferred OP Units

Included in preferred OP units is $34.7 million of Aspen preferred OP units issued by the Operating Partnership which are convertible into 509,676 shares of the Company's common stock. Subject to certain limitations, at any time prior to January 1, 2024, the holder of each Aspen preferred OP unit at its option may convert such Aspen preferred OP unit into: (a) if the market price of our common stock is $68.00 per share of less, 0.397 common OP units, or (b) if the market price of our common stock is greater than $68.00 per share, that the number of common OP units determined by dividing (i) the sum of (A) $27.00 plus (B) 25% of the amount by which the market price of our common stock exceeds $68.00 per share, by (ii) the per-share market price of our common stock. The current preferred distribution rate is 6.5%.

Lines of Credit

In August, 2015, we amended and restated our senior revolving credit facility with Citibank, N.A. and certain other lenders in the amount of $450.0 million, comprised of a $392.0 million revolving loan and $58.0 million term loan (the "Facility"). The Facility has a four year term ending August 19, 2019, which can be extended for two additional six-month periods at our option, subject to the satisfaction of certain conditions as defined in the credit agreement. The credit agreement also provides for, subject to the satisfaction of certain conditions, additional commitments in an amount not to exceed $300.0 million. If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the Facility may be increased up to $750.0 million. The Facility bears interest at a floating rate based on the Eurodollar rate plus a margin that is determined based on our leverage ratio calculated in accordance with the credit agreement, which can range from 1.40% to 2.25% for the revolving loan and 1.35% to 2.20% for the term loan. As of September 30, 2015, the margin on our leverage ratio was 1.45% and 1.40% on the revolving and term loans, respectively. We had $142.0 million on the revolving loan and $25.0 million on the term loan totaling $167.0 million in borrowings as of September 30, 2015, with a weighted average interest rate of 1.66%. As of December 31, 2014 there was no amount outstanding under our previous credit Facility.

The Facility provides us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under our line of credit, but does reduce the borrowing amount available. At September 30, 2015 and December 31, 2014, approximately $3.4 million and $3.2 million, respectively, of availability was used to back standby letters of credit.

We have a $12.0 million manufactured home floor plan facility renewable indefinitely until our lender provides us at least a twelve month notice of their intent to terminate the agreement. The interest rate is 100 basis points over the greater of the prime rate as quoted in the Wall Street Journal on the first business day of each month or 6.0%. At September 30, 2015, the effective interest rate was 7.0%.  There was no outstanding balance at September 30, 2015 and there was $5.8 million at December 31, 2014.

Covenants

Pursuant to the terms of the Facility, we are subject to various financial and other covenants. The most restrictive of our debt agreements place limitations on secured borrowings and contain minimum fixed charge coverage, leverage, distribution, and net worth requirements. At September 30, 2015, we were in compliance with all covenants.

⁽¹⁾The purchase price allocations for the first and second closings are preliminary and may be adjusted as final costs and final valuations are determined.

⁽²⁾ To estimate the fair value of the common OP units at the valuation date, we utilized the market approach, observing public price of our common stock.

⁽³⁾ To estimate the fair value of the Series A-4 preferred OP units and the Series A-4 Preferred Stock at the valuation date, we utilized an income approach. Under this approach, we used the Binomial Lattice Method.

The amount of revenue and net income included in the Consolidated Statements of Operations related to the Green Courte properties for the three and nine months ended September 30, 2015 is set forth in the following table (in thousands):

Transaction costs of approximately $1.7 million and $2.4 million and $13.2 million and $4.3 million have been incurred for the three and nine months ended September 30, 2015 and 2014, respectively, and are presented as “Transaction costs” in our Consolidated Statements of Operations.

Dispositions

During the nine months ended September 30, 2015, we completed the sales of four MH communities. Pursuant to Accounting Standards Update ("ASU") 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) - Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity"("ASU 2014-08"), the disposals of the communities do not qualify for presentation as a discontinued operation, as the sales do not have a major impact on our operations and financial results and do not represent a strategic shift. Additionally, the communities are not considered an individually significant component and therefore do not qualify for presentation as a discontinued operation. A gain of $26.9 million is recorded in "Gain on disposition of properties, net" in our Consolidated Statements of Operations. The table below lists the communities we have disposed of during the nine months ended September 30, 2015.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

We have elected to be taxed as a real estate investment trust (“REIT”) pursuant to Section 856(c) of the Internal Revenue Code of 1986 (“Code”), as amended. In order for us to qualify as a REIT, at least 95% of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute annually at least 90% of its REIT ordinary taxable income to its stockholders.

Qualification as a REIT involves the satisfaction of numerous requirements (i.e., some on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are only limited judicial or administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation which requires us to continually monitor our tax status. We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT for the quarter ended September 30, 2015.

As a REIT, we generally will not be subject to United States ("U.S.") federal income taxes at the corporate level on the ordinary taxable income we distribute to our stockholders as dividends. If we fail to qualify as a REIT in any taxable year, our taxable income could be subject to U.S. federal income tax at regular corporate rates (including any applicable alternative minimum tax). Even if we qualify as a REIT, we may be subject to certain state and local income taxes, U.S. federal income, and excise taxes on our undistributed income.

SHS, our taxable REIT subsidiary, is subject to U.S. federal income taxes. Our deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the bases of such assets and liabilities as measured by tax laws. Deferred tax assets are reduced, if necessary, by a valuation allowance to the amount where realization is more likely than not assured after considering all available evidence. Our temporary differences primarily relate to net operating loss carryforwards and depreciation. A federal deferred tax asset of $1.0 million is included in "Other assets, net," in our Consolidated Balance Sheets as of September 30, 2015 and December 31, 2014.

We had no unrecognized tax benefits as of September 30, 2015 and 2014. We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of September 30, 2015.

We classify certain state taxes as income taxes for financial reporting purposes. For instance, we record Texas Margin Tax as income tax in our financial statements, and recorded a provision for state income taxes of approximately $0.1 million for the three months ended September 30, 2015 and 2014, and $0.3 million for the nine months ended September 30, 2015 and 2014.

SHS is currently under examination by the Internal Revenue Service ("IRS") for the 2013 tax year. To date, we have not received any formal notices of proposed adjustments from the IRS related to this or any other examination periods.
